Waterbody outlet is disconnected from waterbody

[shorvath-noaa]

Looking at file nextgen_03S.gpkg, waterbody (hl_link) 16769792 has two WBIn nodes and one WBOut node. However, the WBOut node is not connected either of the WBIn nodes (see image below).

Obtaining waterbody connections from the NWMv2.1 route_link file and comparing them to the wb-IDs in the 'network' table yields the following crosswalk table:

The WBOut node is nex-1578896, with segments wb-1578895 and wb-1578897 feeding into it. It appears these segments are not part of the NHD waterbody connection from NWMv2.1.
